Experiencing Error 1402 when trying to install a program can be frustrating and confusing. This error message indicates that there is an issue with accessing a specific registry key during the installation process. Understanding the causes and potential solutions for this error can help resolve the issue and successfully install the desired program.
Troubleshooting Steps for Common Issues
1. Check for Administrative Rights: Ensure that you are logged in as an administrator on your Windows 10 or Windows 7 operating system. User Account Control may prevent you from accessing certain registry keys if you are not logged in as an administrator.
2. Use the Registry Editor: Navigate to the registry editor by pressing the Windows key + R, typing “regedit” and pressing Enter. Once in the registry editor, locate the key mentioned in the error message: UNKNOWN\Components\.
3. Check Permissions: Right-click on the key and select “Permissions”. Ensure that the appropriate user accounts have full control permissions. If not, make the necessary changes by clicking on “Advanced” and then “Change Permissions”.
4. Take Ownership: If you are still unable to access the key, you may need to take ownership of it. Right-click on the key, select “Permissions”, then “Advanced”, and finally “Change” next to the owner’s name. Select your user account and click “OK”.
5. Perform a Clean Boot: Sometimes third-party software or services can interfere with the installation process. Perform a clean boot by typing “msconfig” in the start menu and disabling all non-Microsoft services and startup programs. Restart your computer and attempt the installation again.
6. Use Microsoft’s Fix It Tool: Microsoft offers a Fix It tool that can automatically fix issues with Windows installations. Download and run the tool from the Microsoft website to see if it resolves the error 1402.
7. Contact Microsoft Support: If you have tried all the troubleshooting steps and are still encountering the error, it may be necessary to contact Microsoft’s technical support for further assistance.
Reset Registry Permissions to Defaults
Resetting Registry Permissions to Defaults
To reset registry permissions to defaults, you can use the SubInACL tool provided by Microsoft to change the registry permissions to default settings.
First, download and install the SubInACL tool from the Microsoft website. Once installed, open a Command Prompt with administrative privileges.
Next, navigate to the directory where SubInACL is installed using the ‘cd’ command. For example, if it is installed in the C:\Program Files (x86)\Windows Resource Kits\Tools directory, you would type ‘cd C:\Program Files (x86)\Windows Resource Kits\Tools’ and press Enter.
Once in the correct directory, you can use the SubInACL tool to reset registry permissions. Use the following command: subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f /grant=restricted=r /grant=users=r /grant=”creator owner”=f /grant= “power users”=r
This command will reset the permissions for the HKEY_LOCAL_MACHINE registry key to their default settings. You can also use this command for other registry keys as needed.
After running the command, restart your computer for the changes to take effect. This should reset the registry permissions to their default settings and resolve any issues related to error 1402.
It’s important to note that modifying the registry can have serious consequences if done incorrectly. Always back up your registry before making any changes, and proceed with caution.
By using the SubInACL tool to reset registry permissions, you can resolve the error 1402 and ensure that your system operates as intended.
Perform a Clean Reinstallation of Software
1. First, ensure that you have administrative privileges on your computer. If you are not already a superuser, you may need to log in with an account that has the necessary permissions to make changes to the Windows operating system.
2. Next, navigate to the Control Panel in Windows. You can access the Control Panel by clicking on the Start menu and searching for “Control Panel” or by right-clicking on the Windows icon in the bottom left corner of your screen and selecting “Control Panel” from the context menu.
3. In the Control Panel, locate the option for “Programs” or “Programs and Features” and click on it to open the list of installed programs on your computer.
4. Find the software that is causing the error and uninstall it from your system. You can do this by clicking on the program in the list and selecting the “Uninstall” option.
5. Once the software has been successfully uninstalled, you will need to reinstall it. Locate the original installation file or download a new copy from the software provider’s website.
6. Run the installation file and follow the on-screen prompts to reinstall the software on your computer.
7. After the software has been reinstalled, restart your computer to ensure that any changes made during the installation process are applied.
By performing a clean reinstallation of the software, you can often resolve issues such as the “Error 1402 Could not Open Key UNKNOWN\Components\ Installation” error. If you continue to experience problems, you may need to seek technical support from the software provider or a knowledgeable resource such as a computer technician or a technical support knowledge base.
